fix_dhcp_hack

=============

Sometimes, on certain Linux distributions, your network interfaces might not get DHCP assigned to them due to bugs. This Ansible role aims to solve this issue for any distribution, but each one may have its own specific solution.

Currently, the only distribution with this problem is Debian, so this role won't do anything for other distributions.

Known Issues

Debian

As of August 16, 2019, Debian testing does not update the /etc/network/interfaces file correctly. This means that after a reboot, you won't receive a DHCP lease. It's strange because, initially, even though the enp6s0 network interface starts up without an entry in /etc/network/interfaces, you still get DHCP. However, after rebooting, you won't be able to SSH into the system because DHCP won't be assigned to the interface.

Requirements
